Maybe a lot of guys here already had the problem with Ati video cards when using VMR9 render; the black color seems a little bit grey, although some hacks in the Windows registry solves this issue (i.e. 'UseBT601CSC'). But Nvidia is a new thing to me now, since I bought a 9600GT last week. The thing is that now the grey problem appears in all video renders, no matter what I do (codecs, MPC, VLC, MPlayer...).

The first frame of this video (http://download.nvidia.com/downloads/nZone/videos/PureVideo_1080p.wmv) is a good example; it's suposed to be 100% black. Here's the result with my 9600GT + latest nVidia drivers + MPC clsid + FFDShow latest nightly build:

Force (HQ) RGB32 in FFDShow!

Thanks for your reply, but the problem isn't with FFDShow. Even using WMV default codec (that comes with Windows) or using VLC the problem persists. I think that the problem has something to do with nVidia driver.

Do what I said. I had the same problem on Vista with my ATI card. Enable decoding for WMV in FFDShow (select wmv9)

Ok. I already tried, but doesn't help. :(

BTW, what you do when you want to use a no-FFDShow decoder? AFAIK, the Ati problem appears only with VMR9 or EVR, and you can fix it using a very simple reg hack.

CoreAvc also allows RGB32

You can also set FFDshow to accept all colorspaces as inputs; it'll insert itself into the filter chain, and you can use it to convert even if its not being used as the decoder.
